I got up to the top of the hill after the round-about yesterday and took a break at the beginning of the 'old' expert loop, and noticed a whole heap of poison ivy on either side there. Would pretty much be impossible to enter this trail without getting it all over your legs.
So, FYI everyone.
I do have the herbicide to kill this stuff, but I don't know if it is legal for me to spray it on county property (I do have a state pesticides license). I'd be happy to give it a squirt next time I am out there.
Also, there is that boxelder that blew down in the sumac patch, with the root now sticking up in the trail. I might be able to tackle it with my chain saw, even a hand saw might do it, but I'm not sure when I'll be out there again (MAAAAYYbe tomorrow night?).
